By means of molecular designing, a series of sodium branched-alkyl benzene sulfonates weresynthesized through seven process, involving Frieded-Crafts reaction, Grignard reaction, sulfonationand neutralization. Those isomers have similar structure, carbons of same quantity, but the position ofalkylaryl dissimilarity. Liner fat acid, metaxylene and halogenated hydrocarbon of different carbonnumber were used as the starting materials. Optimum processing condition was confirmed consideringinfluence of a series of reaction factors such as feed proportioning, quantity of catalysts, quantitysolvent, reaction time, temperature and pressure. Eight kinds of isomers of sodium hexadecylxylolsulfonates were finally synthesized, and characterized by FT-IR.
